At mouthful end 26, and the flange 52 of shell 22 curve inwardly (such as by rotation or die forging) with by cover board 50, outlet bearing 48,
The bulb 38 of back lining bearing 42 and ball stud 36 is limited in the open pore of shell 22.Boots set 54 is further provided for against ball
The shank 40 of hook bolt 36 is simultaneously sealed against cover board 50 and shell 22, and the lubricant of such as grease is sealed in shell 22
In hole and for pollutant to be maintained at outside the inner hole of shell 22.In this exemplary embodiment, boots set 54 against lid
That one end that plate 50 seals is sandwiched between cover board 50 and outlet bearing 48.This one end of boots set 54 further includes at least partly embedding
Enter Belleville washer 56 (also referred to as spring washer) therein, for applying bias force against bulb spiral shell to outlet bearing 48
The bearing surface of 38 pairs of the bulb outlet bearing 48 of bolt 36 preloads.
In the exemplary embodiment of ball and socket joint component 20, the substantially closed first end 24 and backing axis of shell 22
Holding 42 has a coaxial lubricant aperture 58, and 60, and lubricating grease accessory is accommodated and is used in lubricant aperture 58 in the housing
Lubricating grease or any suitable lubricant are transported in the inner hole of shell 22, to reduce bearing 42,48 and ball stud 36
Friction between bulb 38.
Back lining bearing 42 further includes multiple holes or lubricant depression 62,64, (or any for receiving and storing lubricating grease
Other lubricants) to lubricate the region of back lining bearing 42, otherwise the region will obtain during steering or suspension operate
It seldom lubricates or does not lubricate.That is, lubricant depression 62,64 is used as grease pond, for temporarily storage to be oily when needed
Rouge and release grease.In this way, compared with the back lining bearing of no lubricant depression, with 38 He of spherical bulb of back lining bearing 42
Inner bearing face 44 is mutually worn, and the lubrication between contact surface is improved.In this exemplary embodiment, multiple lubricant depressions
62,64 be only partially but not completely through the first lubricant depression 62 of back lining bearing 42, and multiple lubricants are recessed
Cave 62,64 is the second lubricant depression 64 of complete penetration back lining bearing 42.In this exemplary embodiment, lubricant depression
62,64 are substantially evenly separated from each other, to provide being substantially evenly distributed for lubricant on the inner bearing face of back lining bearing 42.
Referring now to Fig. 2-4, back lining bearing 42 further includes the multiple lubricant tanks 66,68,70 being formed in its bearing surface.
Multiple lubricant tanks 66,68,70 are the first lubricant tanks 66, pass through hemispherical bending part 44 and circle from lubricant aperture 60
Cylindrical section 46 extends to the opposite side of back lining bearing 42, for lubricant to be conveyed through back lining bearing 42 and enters backing axis
It holds in the gap between 42 and outlet bearing 48.The exemplary embodiment includes the first groove of a total of three 66, and these
One groove 66 is substantially evenly spaced apart about 120 ° each other.
Multiple lubricant tanks 66,68,70 in the bearing surface of back lining bearing 42 are the second lubricant tanks 68, from backing
The lubricant aperture 60 of bearing 42 extends to multiple lubricant depressions 62,64, they further pass through multiple lubricant tanks 70 and connect
It connects, the multiple lubricant tank 70 further extends into the upper space 63 of back lining bearing 42.The bearing surface 44 of back lining bearing 42
Further include third group lubricant tank 66, further extends between lubricant depression 62,64, and prolong from lubricant aperture 60
Reach the upper space 63 of back lining bearing 42.When ball-and-socket component 20 adds lubricant grease and supplement grease for the first time, lubricant is logical
The lubricant aperture 58,60 crossed in shell 22 and back lining bearing 42 is injected.As shown in figure 4, some lubricants are opened from lubricant
Mouth 60 flows through the first slot 66 and passes through back lining bearing 42.Remaining lubricant flows through the second lubricant tank 68 and enters multiple lubricants
Depression 62,64.Once these lubricant depressions 62,64 are full of lubricant, then additional lubricant flows through third lubricant tank 70
And enter other lubricant depression 62,64.Therefore, during a simple addition grease, mechanician infuses in addition to tradition
Any specific purpose tool is not necessarily to other than oil gun, it will be able to be rapidly filled with lubricant depression 62,64.
Another aspect of the present invention is a kind of method for manufacturing ball-and-socket component 20 (such as ball-and-socket component 20 shown in FIG. 1).
Method includes the following steps: preparation has the shell 22 of inner hole, which is extended to along axis A from closed first end 24
Open second end 26.This method continues that will there is bearing surface and the back lining bearing of lubricant aperture 60 42 to be inserted into shell
Step in 22 inner hole.This method continues following steps: the bulb 38 of ball stud 36 is inserted into the inner hole of shell 22
In, so that the bearing surface of the outer surface in bulb 38 and back lining bearing 42 is in surface-to-surface contact, to facilitate shell 22 and bulb spiral shell
Relative rotation between bolt 36.This method continues the step of lubricant is injected the inner hole of shell 22.This method continue into
Row following steps: lubricant is drawn by least one lubricant tank 66,68,70 being formed in 42 bearing surface of back lining bearing
It leads at least one lubricant depression 62,64, which is formed in back lining bearing 42 and extends deficiency
With complete penetration back lining bearing 42, with lubricator to fill lubricant depression 62,64.Specifically, in the illustrative methods,
Lubricant is conducted through multiple second lubricant tanks 68 from lubricant aperture 60 and enters multiple lubricant depressions 62, and 64, and
Multiple third lubricant tanks 70 are conducted through from some of lubricant depressions 62,64 and reach other lubricant depressions 62,
64。
Obviously, in view of above-mentioned introduction, many modifications and variations of the present invention are possible.It is therefore to be understood that
In scope of the appended claims, the present invention can be implemented in the mode different from specific descriptions.
